Canon PowerShot A630 review

The camera is all that a novice can want. You can read that in the many posts allready. But ... I returned mine. See problems

Problems:

All the movies I've taken have a anoying hiss. A very audible high pitch. It was that anoying that I brought it back to the store. Apparently a few other powershot camera's also have the same problem. (there's not much written about this problem I've noticed) I;m now considering the canon s-2 or s-3. But I wander if they have the same problem...
